</div> <!----></div> <div class="_3ooJE-Ce_0"></div></div><div class="_2NKpEZ4f_0"><div class="_2VrPoUeX_0"><h2>课程介绍</h2> <!----></div> <div class="_3uBK1dPI_0 _18IFJWYN_0"><div class="_3CegnU7h_0"><p>数据库是一个综合系统，其背后是发展了几十年的数据库理论。也许你会觉得数据库并不难，因为你可以熟练地写出SQL，也可以在各个客户端里玩得游刃有余。但就以最常见的MySQL为例，作为程序员，你在使用MySQL的过程中，是不是曾经遇到过类似的问题：</p>
<ol>
<li>为什么我的count(*)这么慢？</li>
<li>为什么我建了索引，却根本没有效果？</li>
<li>为什么我只查一行的语句，也执行这么慢？</li>
<li>MySQL对于大表要怎么优化？</li>
</ol>
<p>之前，你大概都是通过搜索别人的经验来解决问题。你有没有想过，如果能够理解MySQL的工作原理，那么在遇到问题的时候，是不是就能更快地直戳问题的本质？比如说，知道了索引的实现原理，那遇到索引问题的时候，你是不是就能从原理的角度，推断可能的解决方案？</p>
<p>本课程将会以实战中的常见问题为切入点，带你剖析现象背后的本质原因。更重要的是，本课程还将通过几条主线为你串起各个零散的知识点，再由线到面带你构建MySQL知识体系。</p>
<p>在这个课程里，丁奇将会结合自己十多年来通过MySQL源码找答案的经历，和你分享一条高效的学习路径，旨在给你一个从理论到实战的系统性指导，让你少走弯路，彻底搞懂MySQL。</p>
<p>本课程共包括两大模块。</p>
<p><strong>模块一，基础篇</strong>。为你深入浅出地讲述MySQL核心知识，涵盖MySQL基础架构、日志系统、事务隔离、锁等内容。</p>
<p><strong>模块二，实践篇</strong>。将从一个个关键的数据库问题出发，分析数据库原理，并给出实践指导。每个问题，都不只是简单地给出答案，而是从为什么要这么想、到底该怎样做出发，让你能够知其所以然，都将能够解决你平时工作中的一个疑惑点。</p>
